Released in 1998 on Atlantic Records, the album was not a commercial success, but achieved some critical acclaim. Stephen Thomas Erlewine of Allmusic gave the album 4 out of 5 stars, declaring "12 Bar Blues is an unpredictable, carnivalesque record confirming that Weiland was the visionary behind STP's sound. He's fascinated by sound, piling on layers of shredded guitars, drum loops, and keyboards, making sure that each song sounds drastically different from its predecessor."[8] David Fricke of Rolling Stone awarded the album 3.5 out of 5 stars and declared that "12 Bar Blues isn't really a rock album, or even a pop album. Weiland, out on his own, has simply made an honest album – honest in its confusion, ambition and indulgence. It was worth the risk." but also remarked that "Maybe it's a little early for Scott Weiland to be going the solo way."[9]Pitchfork Media stated upon its release that "12 Bar Blues is easily the most innovative album Weiland has ever produced for public consumption,"[10] while Entertainment Weekly wrote that "the LP's sheer invention and hooks will make your indulgence worthwhile."[11]

Album
–
Album, is a collection of audio recordings issued as a single item on CD, record, audio tape, or another medium. Albums of recorded music were developed in the early 20th century, first as books of individual 78rpm records, vinyl LPs are still issued, though in the 21st century album sales have mostly focused on compact disc and MP3 formats. The audio cassette was a format used from the late 1970s through to the 1990s alongside vinyl, an album may be recorded in a recording studio, in a concert venue, at home, in the field, or a mix of places. Recording may take a few hours to years to complete, usually in several takes with different parts recorded separately. Recordings that are done in one take without overdubbing are termed live, the majority of studio recordings contain an abundance of editing, sound effects, voice adjustments, etc. With modern recording technology, musicians can be recorded in separate rooms or at times while listening to the other parts using headphones. Album covers and liner notes are used, and sometimes additional information is provided, such as analysis of the recording, historically, the term album was applied to a collection of various items housed in a book format. In musical usage the word was used for collections of pieces of printed music from the early nineteenth century. Later, collections of related 78rpm records were bundled in book-like albums, the LP record, or 33 1⁄3 rpm microgroove vinyl record, is a gramophone record format introduced by Columbia Records in 1948. It was adopted by the industry as a standard format for the album. Apart from relatively minor refinements and the important later addition of stereophonic sound capability, the term album had been carried forward from the early nineteenth century when it had been used for collections of short pieces of music. Later, collections of related 78rpm records were bundled in book-like albums, as part of a trend of shifting sales in the music industry, some commenters have declared that the early 21st century experienced the death of the album. Sometimes shorter albums are referred to as mini-albums or EPs, Albums such as Tubular Bells, Amarok, Hergest Ridge by Mike Oldfield, and Yess Close to the Edge, include fewer than four tracks. There are no rules against artists such as Pinhead Gunpowder referring to their own releases under thirty minutes as albums. These are known as box sets, material is stored on an album in sections termed tracks, normally 11 or 12 tracks. A music track is a song or instrumental recording. The term is associated with popular music where separate tracks are known as album tracks. When vinyl records were the medium for audio recordings a track could be identified visually from the grooves

Alternative rock
–
Alternative rock is a genre of rock music that emerged from the independent music underground of the 1980s and became widely popular in the 1990s and 2000s. In this instance, the word refers to the genres distinction from mainstream rock music. The terms original meaning was broader, referring to a generation of musicians unified by their debt to either the musical style or simply the independent. Ethos of punk rock, which in the late 1970s laid the groundwork for alternative music, Alternative rock is a broad umbrella term consisting of music that differs greatly in terms of its sound, its social context, and its regional roots. Most of these subgenres had achieved minor mainstream notice and a few bands representing them, such as Hüsker Dü, with the breakthrough of Nirvana and the popularity of the grunge and Britpop movements in the 1990s, alternative rock entered the musical mainstream and many alternative bands became successful. By the end of the decade, alternative rocks mainstream prominence declined due to a number of events that caused grunge and Britpop to fade, emo attracted attention in the larger alternative rock world, and the term was applied to a variety of artists, including multi-platinum acts. Post-punk revival artists such as Modest Mouse and The Killers had commercial success in the early, before the term alternative rock came into common usage around 1990, the sort of music to which it refers was known by a variety of terms. In 1979, Terry Tolkin used the term Alternative Music to describe the groups he was writing about, in 1979 Dallas radio station KZEW had a late night new wave show entitled Rock and Roll Alternative. College rock was used in the United States to describe the music during the 1980s due to its links to the radio circuit. In the United Kingdom, dozens of small do it yourself record labels emerged as a result of the punk subculture, according to the founder of one of these labels, Cherry Red, NME and Sounds magazines published charts based on small record stores called Alternative Charts. The first national chart based on distribution called the Indie Chart was published in January 1980, at the time, the term indie was used literally to describe independently distributed records. By 1985, indie had come to mean a particular genre, or group of subgenres, at first the term referred to intentionally non–mainstream rock acts that were not influenced by heavy metal ballads, rarefied new wave and high-energy dance anthems. The use of alternative gained further exposure due to the success of Lollapalooza, for which festival founder, in the late 1990s, the definition again became more specific. Defining music as alternative is often difficult because of two conflicting applications of the word, the name alternative rock essentially serves as an umbrella term for underground music that has emerged in the wake of punk rock since the mid-1980s. Alternative bands during the 1980s generally played in clubs, recorded for indie labels. Sounds range from the gloomy soundscapes of gothic rock to the guitars of indie pop to the dirty guitars of grunge to the 1960s/1970s revivalism of Britpop. This approach to lyrics developed as a reflection of the social and economic strains in the United States and United Kingdom of the 1980s, by 1984, a majority of groups signed to independent record labels mined from a variety of rock and particularly 1960s rock influences. This represented a break from the futuristic, hyper-rational post-punk years

MTVs influence on its audience, including issues involving censorship and social activism, has also been a subject of debate for several years, in recent years, MTV had struggled with the secular decline of music-related cable media. In April 2016, MTV announced it would start to return to its original music roots with the reintroduction of the classic MTV series MTV Unplugged. It was also reported that the series MTV Cribs would be making a return on Snapchat, MTV has spawned numerous sister channels in the US and affiliated channels internationally, some of which have gone independent. As of July 2015, approximately 92,188,000 US households have received MTV, several earlier concepts for music video-based television programming had been around since the early 1960s. The Beatles had used music videos to promote their records starting in the mid-1960s, CBS rejected the idea, but Williams premiered his own musical composition Classical Gas on the Smothers Brothers Comedy Hour, where he was head writer.

Pittman, who later became president and chief executive officer of MTV Networks. Pittman had test-driven the music format by producing and hosting a 15-minute show, Album Tracks, the inspiration for PopClips came from a similar program on New Zealands TVNZ network named Radio with Pictures, which premiered in 1976. The concept itself had been in the works since 1966, when record companies began supplying the New Zealand Broadcasting Corporation with promotional music clips to play on the air at no charge. Few artists made the trip to New Zealand to appear live. A shortened version of the shuttle launch ID ran at the top of hour in various forms. The first music video shown on MTV was The Buggles Video Killed the Radio Star and this was followed by the video for Pat Benatars You Better Run. Sporadically, the screen would go black when an employee at MTV inserted a tape into a VCR, MTVs lower third graphics that appeared near the beginning and end of music videos would eventually use the recognizable Kabel typeface for about 25 years

Accordion
–
Accordions are a family of box-shaped musical instruments of the bellows-driven free-reed aerophone type, colloquially referred to as a squeezebox. A person who plays the accordion is called an accordionist, the concertina and bandoneón are related, the harmonium and American reed organ are in the same family. The instrument is played by compressing or expanding the bellows while pressing buttons or keys, causing pallets to open and these vibrate to produce sound inside the body. Valves on opposing reeds of each note are used to make the instruments reeds sound louder without air leaking from each reed block. The performer normally plays the melody on buttons or keys on the manual. The accordion is widely spread across the world, nevertheless, in Europe and North America, some popular music acts also make use of the instrument. Additionally, the accordion is used in cajun, zydeco, jazz music. The piano accordion is the official city instrument of San Francisco, the oldest name for this group of instruments is harmonika, from the Greek harmonikos, meaning harmonic, musical. Today, native versions of the accordion are more common. These names refer to the type of accordion patented by Cyrill Demian, accordions have many configurations and types. Similar to a bow, the production of sound in an accordion is in direct proportion to the motion of the player. The bellows is located between the right- and left-hand manuals, and is made from pleated layers of cloth and cardboard, with added leather and metal. It is used to pressure and vacuum, driving air across the internal reeds and producing sound by their vibration. These boxes house reed chambers for the right- and left-hand manuals, each side has grilles in order to facilitate the transmission of air in and out of the instrument, and to allow the sound to better project. The grille for the manual is usually larger and is often shaped for decorative purposes. The right-hand manual is used for playing the melody and the left-hand manual for playing the accompaniment. The manual mechanism of the instrument either enables the air flow, or disables it, the different types have varying components. All instruments have reed ranks of some format, the most typical accordion is the piano accordion, which is used for many musical genres

Cello
–
The cello or violoncello is a bowed or plucked string instrument with four strings tuned in perfect fifths. The strings from low to high are generally tuned to C2, G2, D3 and A3 and it is a member of the violin family of musical instruments, which also includes the violin and viola and the double bass. The cello is used as a musical instrument, as well as in chamber music ensembles, string orchestras, as a member of the string section of symphony orchestras. It is the second-largest and second lowest bowed string instrument in the symphony orchestra. Cello parts are written in the bass clef, but both tenor clef and treble clefs are used for higher-range parts, both in orchestral/chamber music parts and in solo cello works. A person who plays the cello is called a cellist or violoncellist, in a small Classical ensemble, such as a string quartet, the cello typically plays the bass part, the lowest-pitched musical line of the piece. In orchestra, in Baroque era and Classical music period, the cello plays the bass part. In Baroque era music, the cello is used to play the basso continuo bassline, in a Baroque performance, the cello player might be joined by other bass instruments, playing double bass, viol or other low-register instruments. The name cello is a contraction of the Italian violoncello, which means little violone, in modern symphony orchestras, it is the second largest stringed instrument. Thus, the name contained both the augmentative -one and the diminutive -cello. By the turn of the 20th century, it had become common to shorten the name to cello and it is now customary to use cello without apostrophe as the full designation. Viol is derived from the viola, which was derived from Medieval Latin vitula. Cellos are tuned in fifths, starting with C2, followed by G2, D3 and it is tuned in the same intervals as the viola, but an octave lower. Unlike the violin or viola but similar to the double bass, the cello is most closely associated with European classical music, and has been described as the closest sounding instrument to the human voice. The instrument is a part of the orchestra, as part of the string section. A large number of concertos and sonatas have been written for the cello, among the most well-known Baroque works for the cello are Johann Sebastian Bachs six unaccompanied Suites. The Prelude from the First Suite is particularly famous, romantic era repertoire includes the Robert Schumann Concerto, the Antonín Dvořák Concerto as well as the two sonatas and the Double Concerto by Johannes Brahms. The cello is increasingly common in traditional music, especially Scottish fiddle music

Record producer
–
A record producer or music producer oversees and manages the sound recording and production of a band or performers music, which may range from recording one song to recording a lengthy concept album. A producer has many roles during the recording process, the roles of a producer vary. The producer may perform these roles himself, or help select the engineer, the producer may also pay session musicians and engineers and ensure that the entire project is completed within the record companies budget. A record producer or music producer has a broad role in overseeing and managing the recording. Producers also often take on an entrepreneurial role, with responsibility for the budget, schedules, contracts. In the 2010s, the industry has two kinds of producers with different roles, executive producer and music producer. Executive producers oversee project finances while music producers oversee the process of recording songs or albums. In most cases the producer is also a competent arranger, composer. The producer will also liaise with the engineer who concentrates on the technical aspects of recording. Noted producer Phil Ek described his role as the person who creatively guides or directs the process of making a record, indeed, in Bollywood music, the designation actually is music director. The music producers job is to create, shape, and mold a piece of music, at the beginning of record industry, producer role was technically limited to record, in one shot, artists performing live. The role of producers changed progressively over the 1950s and 1960s due to technological developments, the development of multitrack recording caused a major change in the recording process. Before multitracking, all the elements of a song had to be performed simultaneously, all of these singers and musicians had to be assembled in a large studio and the performance had to be recorded. As well, for a song that used 20 instruments, it was no longer necessary to get all the players in the studio at the same time. Examples include the rock sound effects of the 1960s, e. g. playing back the sound of recorded instruments backwards or clanging the tape to produce unique sound effects. These new instruments were electric or electronic, and thus they used instrument amplifiers, new technologies like multitracking changed the goal of recording, A producer could blend together multiple takes and edit together different sections to create the desired sound. For example, in jazz fusion Bandleader-composer Miles Davis album Bitches Brew, producers like Phil Spector and George Martin were soon creating recordings that were, in practical terms, almost impossible to realise in live performance. Producers became creative figures in the studio, other examples of such engineers includes Joe Meek, Teo Macero, Brian Wilson, and Biddu

Chord progression
–
A chord progression or harmonic progression is a succession of musical chords. Chord progressions are the foundation of harmony in Western musical tradition, in tonal music, chord progressions have the function of establishing or contradicting a tonality. Chord progressions are usually expressed by Roman numerals, a chord may be built upon any note of a musical scale, therefore a seven-note scale allows seven basic chords, each degree of the scale becoming the root of its own chord. A chord built upon the note A is an A chord of some type The harmonic function of any particular chord depends on the context of the chord progression in which it is found. The diatonic harmonization of any major results in three major triads. They are based on the first, fourth, and fifth scale degrees and these three triads include, and therefore can harmonize, every note of that scale. The same scale also provides three relative minor chords, one related to each of the three major chords, separate from these six common chords there is one degree of the scale, the seventh, that results in a diminished chord. In addition, extra notes may be added to any chord, if these notes are also selected from the original scale the harmony remains diatonic. If new chromatic intervals are introduced then a change of scale or modulation occurs and this in turn may lead to a resolution back to the original key, so that the entire sequence of chords helps create an extended musical form. In western classical notation, chords built on the scale are numbered with Roman numerals, other forms of chord notation have been devised, from figured bass to the chord chart. These usually allow or even require an amount of improvisation. Diatonic scales such as the major and minor scales lend themselves well to the construction of common chords because they contain a large number of perfect fifths. Such scales predominate in those regions where harmony is an part of music, as, for example. Alternation between two chords may be thought of as the most basic chord progression, many well-known pieces are built harmonically upon the mere repetition of two chords of the same scale. The Isley Brothers Shout uses I - vi throughout, three-chord tunes, though, are more common, since a melody may then dwell on any note of the scale. They are often presented as successions of four chords, in order to produce a binary harmonic rhythm, often the chords may be selected to fit a pre-conceived melody, but just as often it is the progression itself that gives rise to the melody. (Common in Elizabethan music, this also underpins the American college song Goodnight Ladies, is the exclusive progression used in Kwela, similar progressions abound in African popular music. They may be varied by the addition of sevenths to any chord or by substitution of the minor of the IV chord to give, for example

Blues progressions influenced a great deal of 20th century American popular music

The Mills Brothers' recording of "Till Then" looked forward both to the end of World War II and to the popular music of the 1950s. (Courtesy of the Fraser MacPherson estate c/o Guy MacPherson)

The key note or tonic of a piece of music is called note number one, the first step of the ascending scale. Chords built on each scale degree are numbered in the same way so that, for example, in the key of C, the progression E minor - F - G can be generally described as a three - four - five progression.
